The other annoying thing with the aFe is the turbo noise at highway speeds. It's loud, and never goes away.

As for drop ins, I've never liked K&N. Too much work for me to keep the MAF and the filter clean. I find the oil is good, but almost too good at cleaning the charge air. If you live somewhere dry and dusty, you'll need to clean it far more often than recommended intervals.

Dry filters are the way to go, they work very well and won't ruin sensors with oil, and are far easier to clean, dry and reinstall compared to oiled filters.
